DK065G AC DC Converter Control ICs Chip Application for GaN PD65W Mobile Phone Wall Charger Adapter
GaN chip product line:
With one chip to complete GaN power component, PWM control, driver, protection, and other functions (one chip can complete the functions of the original three chips), the number of peripheral components of the power supply chip is greatly reduced, which can not only improve the overall performance of the program (while improving power density and efficiency), but also reduce the PCB board occupation, reduce the size and material costs. More convenient for power supply engineers in the application process, easy to debug, and can accelerate the time-to-market cycle.
Advantages of Gallium Nitride:
Simplify the design of GaN chargers;
Reduce the development difficulty of GaN fast chargers;
Help to realize small size and high efficiency GaN fast charger design.
Improving space utilization;
Reduce the production difficulty;
Speed up the shipment;
Fewer components; Easy to debug; Reduce the cost.
1. GENERAL DESCRIPTION
DK0xxG series is a high performance AC-DC power converter with 650V GaN HEMT device integrated. With quasi-resonant control mode, DK0xxG series can detect the voltage over drain-source voltage across the GaN device and turn on the device when VDS oscillate to the lowest point. Thus, system overall efficiency and EMI performance can be greatly improved.
DK0xxG series greatly simplifies the design and manufacture of AC-DC SMPS, especially those requiring high conversion efficiency and high power density. DK0xxG has complete protection functions including output over-voltage protection (OVP), VCC over-voltage protection, over-temperature protection (OTP), open-loop protection, output over-current protection (OCP), etc.
DK0xxG series adopt PDFN5*6 and DFN8*8 package.
